AT&T has been keeping very quiet about its 4G plans over the past year, letting the other 3 major players freely roll out their respective 4G technologies - HSPA+ for T-Mobile, WiMax for Sprint, and LTE for Verizon. However, after the announcements at this morning's AT&T Developer Summit, it is clear AT&T is seriously stepping up its game.

According to Ralph de La Vega, AT&T's CEO, AT&T has already completed the upgrade of the whole mobile broadband network to HSPA+, or Evolved HSPA, which is the same technology used by T-Mobile that currently offers theoretical speeds of about 21Mbps downstream.

fccIn a word: yes. Wireless carriers in the US (Verizon, AT&T, Sprint, T-Mobile, etc.) have long been deeply opposed to net neutrality over their so-called "mobile broadband" networks, but today they've been given a power they have long desired to see the FCC put into writing.

If you haven't been following the net neutrality saga, you might want to find out what exactly "net neutrality" is, or what it means.

Do you feel the need for speed? Apparently you aren't alone, as Dolphin Browser Mini has just gone into public beta on the Market. The app offers numerous improvements over the regular version of Dolphin Browser as well as the HD version, including:

High speed responsibility [sic]

Speed Dial Homepage

Innovative Menu design

Infinite tabs browsing

Intelligent back & forward button

Like its ancestors, it also features a variety of innovative gestures, bookmark syncing, private browsing, and a host of other features not found in the stock Android browser.

Well, here we are again. Another week, another slew of apps to choose from. For a while there, we were doing an "App of the Week" series and then, for an even longer while, we weren't. I'd like for us to get back on the right path here, so I'm going to fix this.

App of the Week, Season 2: Eclectic Boogaloo

I've been a long time fan of Grooveshark. It is a service that, in my mind, cannot be beaten.

Google's mobile blog released some impressive numbers today in regard to the availability of Google Instant for mobile: the service is now ready for Android 2.2+ and iOS 4 devices in 28 different languages and 40 countries.

If you're a non-US Android (or iOS) user and want to check availability for your locale, simply go to the Google homepage on your device. If "Instant (beta) is off" appears hit "Turn on", and you'll be set to go.

Yelp's mobile app on Android just got an update to version 2.5, introducing just one feature - check-in offers. Check-in offers are new to Yelp but not new in the industry - 4square pioneered the concept, followed by Facebook and SCVNGR. Yelp introduced mobile check-ins in July of this year.

The basic idea is whenever you check into a business using the mobile app, you may be presented with a discount coupon in one of these 3 categories: % off, free item, or fixed discounted price.

We all knew it was coming - Full Tilt Poker Rush Mobile, the first real money poker game on Android, has finally hit the Android Market, and is available for devices running Froyo, due to the Flash 10.1 requirement. The app still bears a beta sticker, so be careful with those hard earned greens of yours. Obviously, it goes without saying that you should also find a stable connection, preferably WiFi, unless you want to fold every hand you get disconnected from.

Millennial Media has released their Mobile Mix for October, and at first sight, the results are fairly impressive. Before diving in, though, it's important to note that the statistics are based on ad clicks, rather than a population sample. However, that doesn't mean they don't help express the overall trends, so with that in mind, let's take a quick look at the highlights.

· This month, for the first time, Android tied with iOS as the largest Smartphone OS on our network, with an 8% increase month-over-month and 37% impression share on our network.

Today’s smartphones are quickly absorbing the functions of other portable devices - PDAs, portable GPS units, and standalone MIDs are a thing of the past - and conventional MP3 players may be next on the cutting block.

Opera Mobile for Android (not to be confused with its Mini brethren) has certainly been long in the making, but according to a recent tweet by @opvard, one of Opera's employees, it's finally around the corner. The tweet didn't reveal much, but it did inform us that the mobile browser is on track for a November 9th release, adding a definitive date to the awesome Next page that we saw yesterday.
